Abstract

Anti-foam compositions suitable for use in detergent powders and liquids are formed from polysiloxane liquids and selected hydrophobic particles. The particles in question are alkylene dialkylamides, polyvalent metal salts of alkyl phosphoric acids or polyvalent alkali metal salts of carboxylic acids, or precursors of any of these.
